Okay.

I thought the INPUT block was always necessary...

at the level of word. Tell me what you think.
There are a lot of methods of `FiniteWord_class` that do not need the
existence of a parent alphabet. That was one of the first clean up that we
did back in 2009: get rid of things that were not necesary.
But then, there are also a lot of methods of `FiniteWord_class` that
*needs* an alphabet. At that time, we choose to allow the user to use such
methods without having previously defined an alphabet. But, I think we
were wrong. If a method needs an alphabet to work reasonably, we should
just raise an error if there were no alphabet assigned to the parent. This
is in accordance to the way I fixed the `abelian_vector` method and added
a deprecation to the alphabet input.
